Found out this nice WordPress for Windows phone app.
Installed it, but always got that Did you wrote your url correctly error and I couldn’t get it working. Tried to write it correctly many times, different ways but no go. Then from that page verified that yes, it works (no it didn’t although it looked first) apiLink is ok, can see the web page, though IE showed http://www.lehtosaari.fi/xmlrpc.php?rsd correctly but Firefox gave after first line this XML Parsing Error: XML or text declaration not at start of entity. Couldn’t at this point figure it out. Then did some surfing on the error codes and Finally found out that Blank line before XML declaration (WordPress) is actually causing this. If you look the source code of the WordPress page, you can see from there if there is blank line and correct it. Then Realized that yes, I changed the theme to something else (SLS) first and immediately after changing that back to Twenty Twelve this got corrected. This should help everyone that is having this problem on your own wordpress and Windows Phone WordPress app.
